I saw those interviews as well. Katy really did come across as a "bubbly little thing" but in a very pleasant way. Sounds like she might have a job in the catering industry if the tennis doesn't work out !!
As for the two guys, I agree as well. Kyle was ..... well, Kyle. As calm in front of the microphone as he is on court. As for Luke, that is the first time I have seen him and I was also surprised to see him discuss his lack of confidence so openly. It may be the case, but he would probably be better advised to keep that to himself. Don't want him giving any undue advantage to an opponent.
And yes, the s***s can be a problem as I have found out to my cost before. Try typing the word mis-hits .......... without the hyphen !!
